IMPROVEMENT IN SPITTOONS.

Specification forming part of Letters Patent No. 136,060, dated February f8, 1873.

To att whom Iit may couce'rm' Beit known that I, JAMEs L. HOWARD, of

, Hartford, in the county of Hartford and State 4view of the same parts, showing the valve open.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates especially to improvements of spittoons which are designed for usein railroad cars. My object is to construct a twopart double side-wall spittoon, and to tit together the parts so that while a very close joint is 'formed the parts are readily separated when desired; also, to construct'the spittoon with a tubular opening through its bottom, and to provide the same with a self-acting valve which will allow the escape through said opening of the juices, but prevent the upward entrance of air through the opening, as will be hereinafter explained. f

The following description oi' my invention will enable others skilled in the art to understand it.

In the accompanying drawing, A B represent the two sections ot' which my improved spittoon is composed. The base section B is a circular pan for receiving the juices, which isl surrounded at its base bya bead, b, above which is a narrow annular bearing, y, and above this extends a proper distance the side wall of the base,` as clearly shown by the two sectional views (,f the drawing. The top section or cap,` A consists of a perforated funnel, a, surrounded by a rim which is nearly equal in width to the height of the base section B, and which is of such diameter at its lower edgethat it will receive into it all that portion 1 of the base B which extends above the, band b. That portion of the cap A which is received upon the bearing y ares alittle downward, and this bearing y has also a slight bevel upward, so that when the cap sectiorrA is pressed down upon the base section as far asthe bead b the points of impingement will be a very close joint; I thus make a close joint on a lvery narrow bearing, which will allow the two sections A B to be readily separated when de` sired-a result which would not be obtained if the bearing y extended to the upper edge of the base section. The base section B is constructed with a tubular opening, s, through the center of its bottom, at the upper end of which is a valve-seat for a valve, I). Surrounding the tube s is a screw-thread for receiving a hanged collar, C, by means of which the base section B is secured to the oor of a car, and also by means of which a hose or pipe can be attached to the tube s for con ducting off fluids. The valve D consists of tioating portion e, of wood, hollow metal, vulcanized rubber, or other suitable light material, a convex head, g, and a loop, f. A stem,V p, prevents the Valve from displacement.

It will be seen from the above description that the annular side of the spittoon which is exposed to severe blows is composed of two walls iitted together bya close joint, which walls will resist all ordinary blows without being bruised or indented; also, that I employ a self-acting oatin g valve for closing the discharge -opening through the bottom of the spittoon, which valve will be buoyed up by Huid in the spittoon, and thus prevent an undue accumulation of fluid therein; and it will also allow a free escape of water through the spittoon in washing out. The valve D also prevents currents of air rising through the spittoon, which would carry with them into a Vcar unpleasant odors, besides being otherwise forming and uniting the two parts in the inanner substantially as described.

2. The seltacting iioating valve D, applied to the tubular outlet s through the base ot' the spittoon, substantially as described.

3. The combination ofthe flanged Vscrewcollar C, the tubular opening s, the valve D, and the spittoon-base B, substantially as de- JAMES L. HOWARD.
